Race car paint has "orange peel" finish for the same reason, supposed to improve flow by disturbing the layer of air that "clings" to the surface.

Cool, forgot that later Maxis would have got the "metric" HIF44. Great find for @kws, he should be able to whip up his own extractors to go with it.

Looks like you've got the holy grail, twin 1.75" carbs on E-series manifold. Are there any numbers on the carbs? E-series has 4 ports, B-series has 2 ports.

Is that a result of better thermal efficiency , or just the extra power allowing a lighter right foot?

No, I think the detailed production records were lost when the Zetland factory closed. Hard to work out from chassis numbers, as each variant was numbered from 1001, so yours is the 572nd Deluxe 1750 manual Coupe. Production was about 200 cars per week, roughly 40% were Deluxe, and 40% Coupes, but I don't know the % for engine and trans. You could probably use a spreadsheet to make a guesstimate. Because your chassis number doesn't start with a "Y", it's probably NZ assembled. If you have the original rego number, you will be able to find out the date first registered, the build date

I certainly never paid anything like that for freight from the US for similar size packages.

Both. Lucas changed from inductive (RVI) to single wire (RVC) in the early 70s, and it appears the Marina started with RVI then changed to RVC. The wiring harness should have the bullet connectors for a RVI, or a wire with a spade connector for the RVC. A GENTLEMAN’S GUIDE TO SMITHS ELECTRONIC TACHOMETERS Wiring a Marina Tachometer

Nice job on the gauges. If you don't have any luck finding a tachometer, I have a spare.

After delivering the filter elements just before Christmas, discovered the base plates were missing, and had to order those too. So another months delay, but what the heck, it's been a while already. Delivered the base plates, and the engine guys were finally able to run the engine safely, without worrying it would suck in a lose bolt or some such. Due to the time it had been there, they had been having to move it around a bit, which wasn't doing the engine any favours, so was recommended to run it under load on the dyno to bed in the rings. Getting it to run properly turned into

Rust in the guards is usually where mud collects, behind the headlights or by the A-pillar. Looks like it might have had ding and not been well repaired?

Nice. Ginger beer's taste literal or figurative?

Dual filament bulb holders in the rear indicators because 70s Aussie cars used them for reversing lights. Select reverse and both rear amber lights illuminate. Can remember dad's XA Falcon doing the same thing.

My first Marina rusted out the bottom of the spare wheel well, might pay to check the drain hose that goes through it is still connected. I haven't seen a "Hinged Kerb Guard" with the flat flap extension, maybe they added that later. Mine only had the oval part. This is the correct top radiator hose on eBay Australia, and the correct bottom radiator hose . The prop centre bearing is supposed to be the same as the Triumph Dolomite, available from Rimmer Bros or off eBay UK. The Marina club do some replacement panels (reproduced from original panels), but it doesn't look like

Rover did an injected version in the '80s (although the S-series had the ports on the right as it was installed the opposite way round to the Maxi) https://www.aronline.co.uk/cars/rover/rover-213-216/vitesse-story/

T5 or T56 from a Camaro should bolt straight up? Did 307 have same bolt pattern as LS1 etc?

FYI Ryco have the filter dimensions on their website. Marina isn't listed, but Z83B is listed under Austin Nomad and Kimberley, and Z23 is listed under Leyland P76 https://www.ryco.co.nz/catalogue/part/index/part/Z83b https://www.ryco.co.nz/catalogue/part/index/part/Z23

Is the oil filter on the sump or the block? Up to mid/late 1973, the oil filter was a Z83B located on the sump, then they changed it to a Z23 located on the block to be consistent with the Six. I got caught out by that, as my Coupe came with a later single carb engine installed, with a different filter to the original twin carb engine (that also came with it). Pay to check if someone's done that engine swap.

Was the wicker riveted through the top of the tube, without a drain hole at the bottom of the tube? Nice work though.

That'll be the carpets, the padded door mappings, and that cast iron twin carb manifold. Fyi, Lynx Australia still list an alloy twin carb manifold for the E-series engine. https://www.lynxauto.com.au/nomad-1500-1750-ohc-2-x-su-1-3-4.html Their single and twin Weber sidedraught manifolds are listed but out of stock.

Strangely, they didn't all get the brake booster. Mags were optional extra (which I've never seen in NZ), but TC had different hubcaps and radial tyres. Centre console and rev counter were most obvious interior improvements. Will upload the 12 page brochure later.
